POOUSHIELD .;H# ve1 a"W,;,LOS Angele ic Applicationflwe 19, 1947; seriar-Nox'isasl'i' (Cl. 1'60--Z68) 1: 2;.Claimsa i1- Thisinvention relates to a swimming poohand like structure.

One chiefobject of-tliisinvention is to provide a shielding device which canbaexthddeasily and quickly-over the entire water surface of the I pool in order to'prevent the falling of chil'dren and animals into th'e-pool while the latter isnot in use and leftunguardedqand="also-as a secondary purpose for= -preventing the falling :or dust, soot or leaves intothe pool' as well' as'for shielding it against the infilience of the sun, so that the water the-pool will remain clear and cool while the pool-is not being used.

Another object; of the present invention-lathe provision of 'a device of thejcharacter described which can be installed easily";andiinexpensively into anyhexisting pool irrespective"or-itssize and shape.

Still another-object ,ofathe present invention is the provision of a device of the character describedwhich can be operated easily by one person even if it is used on a fairly large pool and which can be.expandedover'the'rpo'ol and attached-to the edges of the pool without theuse considerable amount of skill; v

Yet a vstillfurther object of the presentfinven- .tion is the provision of 'a device of thecharacter described which is simple construction, con- .sisting of only a few ineXpensive.,-parts[.thatcan be assembled and installed easily, but which is sturdy, durable, and Well adapted to withstand the influence of the weather and of humidity as well as the rough useage to which devices of this type frequently are subjected.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown.

In said drawings:

Figure 2 is an enlarged fractional top plan view;

Figure 3 is an enlarged broken vertical sectional view at a corner of the pool showing the device partly in section.

*Figureifi isa cross-sectional view'on theasline Figure l '7 is: a side elevation of; another detail;

vertical walls and the :numeraled denotes the bottom of arectangular swimming pool. Anup right stand 3 is placed in one corner section of the pool and is either secured to the bottom 4 by means of screws or inany'other suitable manner and/or is laterally secured to oneof the 20 the stand 3 and is formed as a unit with alongitudinal bearing I5in which ashaft i5 is-r0- tatable; Another shaft I which carries a gear wheel l3 and a bevel wheel l2 is securedto the hanger 6, andthe wheels i2 and 'l3 are connected to one another andare rotatable onthe shaft 7. A'gear wheel M, which is in permanent engagement with the wheel l3,'is secured to the shaft I6 at one side of the bearing i5, while a the upper portion of the wall I a small recess 2 into which extend the wheels l2, l3 and I4, thus making it possible to place the stand 3 as close as possible to the walls I A bolt I0 is vertically extended into the stand 3, and a horizontal bevel wheel 3, whose teeth ll! are in engagement with the wheel l2, and which is provided with a handle 9, is rotatable thereon. A pliable shield l 9, for instance a sheet of plastic material which is covered by, or made as a unit with, a wire mesh or the like, is wound upon the roller l1 and has one of its end portions secured thereto. If the shaft [6 and the roller I! are moderately long, which is the case if the swimming pool is only a few feet wide, the bearing 15 will aiford sufiicient support for the shaft I6. However, if the parts It and I! are of a considerable length, I prefer to extend the outer extremity of the shaft l6 into an additional bearing l8 (Fig. l), which is mounted in a wall I opposite the recess 2.

The edges of the shield l 9 are preferably reinforced and provided with eyelets 20 which are adapted for engaging any suitable fastening means at the upper inner sides of the walls I. I prefer to use as fastening means oval open rings 2| of metal, which are secured to the walls I by 'means of bolts 23, and whose open portions are around the pulley 25 and back, to a hook 28 at the wall I which is opposite the lug 24.

For closing the open pool by means of' th e shield IS, the operator will turn the handle 9 A and the wheel 8, and simultaneously will pull that portion of the rope 26 which runs toward the hook 28. In case of a comparatively small pool, a pulling of the rope 26 toward the hook 28 alone will be sufficient for unwinding the shield l9 from the roller l1. When the free end portion of the unwound shield I9 has reached the wall I to which the lug 24 is attached, the fasteners 2| are connected to the eyelets 20 in the manner illustrated in Figures 5 and 6.

For opening the closed pool, the fasteners 2! are disengaged from the eyelets 20 and then the wheel 8 is rotated, thereby the rope 26 being held. tense, until the entire shield I9 is re-wound upon the roller 11; thereupon the free extremity of the rope 26 is fastened to the hook 28 (Fig. 1). Any

suitable locking mechanism or a chain and padlook (not shown) engaging the handle 9 can be used on the mechanical parts 8, l2, 13 or IQ for preventing safely an unwanted un-winding of the shield 19 off the roller ll.

A box (not shown) or any other suitable cover can be used for covering the mechanical parts of the device, and the cover can be made entirely I or partially removable for making the device accessible for operating it.

Since certain changes may be madein the above article and different embodiments of the invention could be made without departing from the scope thereof, it is' intended that all matter c0ntained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:

1. A swimming pool shield comprising a vertical stand placed in a corner of a swimming pool, a hanger secured to said stand, a transverse roller rotatably carried by said hanger, a flexible, shield horizontally extended over the entire water surface of the pool and being windable upon said roller and provided with means for fastening its edges to the upper wall portions of the pool after it has been unwound from said roller, and a gear wheel having an upright handle being rotatably mounted upon the top portion of said stand and being geared to said roller, all substantially as described.

2. A swimming pool shield comprising a hanger, a transverse horizontal roller which is rotatably carried by a said hanger, an upright stand to which said hanger is secured being placed into a corner section of a swimming pool and resting at its lower end, upon the bottom of the pool, a flexible shield being extended over the entire water surface of the pool being wound upon said roller, a plurality of open ring members being provided on the edges of said shield and connect able to the upper Wall portions of the pool after said shield has been unwound from said roller, and a gear wheel having a handle being rotatably mounted upon the top portion of said stand and being geared to said roller.
